This invention relates to egg case filler machines, and its principalobject is to provide an automatic machine for forming the interlockingstrips that comprise the cross walls of fillers for egg cases, and alsocartons, and I in the completed'egg case filler; inserting the notchedstrips through the slots of the slotted strips, and severing thecompleted filler from the unassembled notched strips. Another object isto provide an egg case filler machine which requires no manual operationwhatsoever and which israpid and highly efficient in operation. 1

With these and other objects and advantages in view, this inventionconsists in an egg case filler machine having automatic mechanism forpunching and slitting sheets of material into strips and assembling thestrips into complete egg case fillers. It further consists in a novelarrangement of dies for punching out the slots and notches in the sheetscombined with feed mechanism for the notched strips, sheet slitting orsevering mechanism for dividing the sheets into strips, and mechanismfor inserting the notched strips into the slots of the slotted strips.

It further consists in the provision of timing mechanism between thevarious elements that operate upon the material for co-ordinating themovements of said elements, whereby the notched strips may be properlyinserted into the slots of the slotted strips.

ihe invent-ion further consists in the several novel features ofconstruction, arrangement and combination of parts hereinafter fully setforth and claimed. 1

As an example of an egg case filler, or other cardboard structure whichmay be made in a machine embodying the present invention,

' the one shown in Fig. 16 of the drawings is illustrative. In this typeof egg case filler, the parallel cross walls which extend in onedirection contain the slots 8, and the parallel cross walls whichintersect the first mentioned cross walls are formed with the opposingof the slots, the notched strips may be inserted through the slots bybending or bowing them to conform to the curved edges of the slots andallowing them to spring back.

into a flat condition with the notched portions straddling theedgeportions of the slotted'strip. An interlocking condition is therebyprovided between the intersecting strips.

Inorder that the details of construction shown and described herein maybe clearly understood, I shall first proceed to explain the generalconstruction and operation of the machine. Two long sheets of cardboardor other suitable egg case filler material, one for the slotted stripsand one for the notched strips, are fed through the machine in anintermittent manner by suitable feed mechanism, and upon entering themachine, one

of the sheets is struck up with suitable dies to form the slots therein,and the other sheet is struck up with suitable dies to form notches andelongated slots that subsequently become the notches. The two sheets runparallel to each other in the machine until they reach ,ppsitionsadjacent an assembling frame.

owever, before the sheet, from which the notched strips areformed,reaches the assembling frame, it encounters a series of knives orcutting disks which slit the sheet into lengthwise extendinn' ribbons orstrips, and

the free ends of said ribbons or strips are thereafter bent uponthemselves along their from the assembling frame.'

the same direction.

The sheet containing the slots is fed into a position above theassembling frame where said sheet is slit transversely to provide aplurality of tranversely extending slotted strips which are insertedinto the assembling frame, and while being inserted therei-nto, they areturned upon their axes so as to stand crosswise of the assembling framespaced apart and in parallel relation to each other with the slots ofeach strip in alignment with the slots of the other strips, after whichthe bent or trough-like end portions of the notched strips are fedthrough the slots of the transversely extending slotted strips.Thereafter, the assembled notched strips are severed from theunassembled notched strips and the completed egg filler is dischargedThe assembling frame is made in two sections opening outwardly from eachother, whereby when the bent notched'strips are released by theassembling frame they straighten out, due to their inherent' resihency,and interlock with the slot-ted strips. During the interval that thesever-ed slotted strips are being fed into the assembling frame anotherlength of the, slottedsheet is fed into the space formerly occupied bythe severed slotted strips, and as the'strip inserting means and stripslitting means for the slotted sheet is retracted, the newly fed portionof the slotted sheet is severed into individual slotted strips foranother filler.

Referring now to the drawings which illustrate one embodiment of theinvention, and first to Figs. 1, 2 and 3, the reference character 20designates the base of the machine which, as shown, is mounted upon legs21. As shown in the drawings, three separate units a, b and a (seeFig. 1) are provided in the one machine, and, inasmuch as these unitsare substantially alike, a description of one unit will sufiice for all.

. Upon the upper and'lower frame members 22 and 23 are bearing brackets24 in which is journalcd an upright die actuating shaft 25 whichcomprises the main driving shaft of each umt, and upon the upper end ofsaid shaft is a gear wheel 26 which may be clutched to the shaft 25 by asuitable clutch 27 (see Fig. 4). Secured to or formed as a part of saidgear wheel 26 is'a beveled gear wheel 28 which meshes with a beveledpinion 29 fast upon a shaft 30 journaled in bearing brackets 31 mountedupon an upright frame 32. Upon the shaft 30 is a pulley 33 which may bedriven from'any suitable source of power, and, as here shown, is beltedto the pulley 34' of an electric motor 35 by a belt 36. It will beunderstood that each of the units a, b and 0 contains a die actuatingshaft 25 and a gear Wheel 26 thereon, and idlers 26" are providedbetween the gear wheels 26 which intermesh with said gear wheels andthus transmit power from the first mentioned shaft 25 ,to thecorresponding shafts I from which the notched strips are formed is shownat B. As shown in the drawings, the

sheet A runs parallel with the sheet B and is arran ed thereabove. Thesheets A and B may be ed from large rolls of filler material.

Ad'acent the receivin end of the machine are t e dies for punc ing theslots and notches in the sheets. The stationary dies for the two sheetsare shown at 37 and 38,

said dies being mounted upon upright members 39 'of the frame, and themovable dies 40 and 41 are carried by dieheads 42 and 43 guided insuitable guideways 44 mounted on the frame.

The heads 42 of the movable dies are actuated by the shaft 25, and arehere shown as connected to operating struts or connecting rods 45 whichhave straps 46 upon their free ends that surround eccentric blocks 47mounted upon the shaft 25. The movable die 40 carries a multiplicity ofpunches 48 which co-operate with openings 49 in the stationary die 37 toform the slots 8 in the sheet A, and the movable die 41 carries amultipliciy of punches 50 which co-operate with openings 51 in thestationary die 38 to form notches 'n, and other elongated holes '12. inthe sheet B, which holes finally become notches in the notched strips,as will be hereinafter explained. The punches of both dies are arrangedin rows extending at right angles is to each other, certain of whichextend lengthwise of the sheets A-and B and the others of which extendat right angles thereto, as is clearly seen in Fig. 2.

The machine illustrated in the drawings is arranged to form the materialand assemble an egg case filler containing thirty-six cells made. up ofseven slotted strips and seven notched strips extending through andinterlocked with the slotted strips. Conse-.

quently, the die 40 contains seven punches for the slots in eachvertical row and the die 41 contains eight punches for the notchesextending in each vertical row. it will be observed that the number ofpunches depends upon the number of strips used in making up of the slotsand notches in the strip required for one complete egg case filler atone operation. The punches at the upper and lower ends of the die 41 aredesigned to form notches in the opposing edges of the sheet B,

which notches are of the reguired depth, and

the intermediate punches said die cut out elongated openings in the bodportion of the sheet (seeFig. 2) which, w en the sheet is slit intoindividual strips, become notches of the same depth as those on theedges of the sheet. While the exact shape of the punches is immaterialto this inventlon broadly considered, the punches for cutting out theslots 8 (see Fig. 17) are shaped to correspond with the said slots, andthe punches for cutting out the notches are shaped to form the notches92 (see Fig. 18), it being understood that the intermediate punches ofthe die 41 punch out holes of twice the length of the notches 'n seen inFig. 18.

Mounted in bearing brackets carried by the frame of the machine is afeed roller 52 which co-operates with a. roller 53 to feed the slottedsheet A to the strip slitting and.

inserting mechanism, which will be hereinafter described, and said feedrolls are rotated in an intermittent manner in timed relation totheaction of the dies and the operation of the strip slitting andinserting mechanism. The mechanism shown for intermittently rotating thefeed rolls 52 and 53 is best shown in Figs. 2, 3 and 5.

On the lower end of the die actuating shaft 25 is a crank wheel 54 whichis connected to a lever 55 by a link 56, and the'lever 55 is connectedto a rack bar 57 by a link 58. The lever 55 is fulcrumed upon theunderside of the frame of the machine and the rack bar 57 is slidablyguided in a guide member 59 also supported upon the underside of theframe. Meshing with the rack bar 57 is a pinion or other toothed wheel60 which is loosely mounted-upon an upright shaft 61 journaled inbearings carried by the frame of the machine, and ratchet clutchmechanism 62 (see also Figs. 6 and 7) is provided between the pinion 60and the shaft 61, which ratchet mechanism is constructed and arranged toclutch the pinion to the shaft whenever the rack bar 57 is moved in thedirection of the arrow thereon in Fig. 5, but not when the rack bar ismoved in the opposite direction. The feed rolls are timed so as torotate while (til e punches are free from the stationary les.

Upon the upper end of the upright shaft 61 and upon the lower end of theshaft 63 of the feed roll 52 are mounted sprocket wheels 64 around whichis trained a sprocket chain 65 for transmitting motion from the uprightshaft 61 to the feed roll 52. It will 7 be observed that the feed rollsremain stationary while the rack bar 57 is moving in a directionopposite to the arrow thereon in Fig. 5, and during this interval ofrest of the feed rolls. the sheet A is being slotted and the slottedstrips are being inserted into the assembling frame. During the movementof the rack bar 57 in the direction of the arrow thereon, the feed rolls52 are rotated thereby advancing the slotted sheet and carrying a lengththereof into position to be acted upon by the strip slitting mechanismand strip inserting mechanism.

Directly beyond the feed rolls 52 and 53 is the strip slitting mechanismand strip inserting mechanism for the slotted strips. As shown in Figs.2 and 3, a reciprocatory frame ()6 is provided which is slidably mountedand guided upon vertical channel shaped guide bars (57 secured to andsupported by the frame of the machine. Rotatably mounted in bracket arms68 carried by the frame 66 are cutting disks or knives 69 (see Fig. 14:)which co-operate with a vertically extending cutting plate or board 70tosever or slit the slotted sheet A along spaced vertical lines into theslotted strips A. I

Supported upon the frame 66 and extending intermediate the cutting disksor knives (39 are strip inserting fingers 71 which are here shown in theform of fiat springs bent up, as illustrated in Fig. 14, and each havingone end ei'ltering a vertical groove 72 (see Fig. 14) in the cuttingboard 7 0. During the interval that the slotted sheet A is fed into theposition occupied when it is severed into strips, the frame 66 and thecutting disks (S9 and strip inserting fingers 71 occupy a' loweredposition with the cutting disks and inserting fingers below the path ofmovement taken by the slotted sheet. This permits; the

sheet to be freely advanced into position contiguous with the cuttingboard 70. After the slotted sheethas been advanced into proper position,the frame 66 and therewith the cutting disks and strip inserting fingersare moved upwardly, the cutting disks being moved across the sheet/andcutting or slitting. the same into .the individual slotted strips A. Thestrip inserting fingers, being formed of resilient material, move freelyupward along the severed strips to a position slightly above the upperedge thereof.

The means shown for reciprocating the frame (56 con'iprises a lever 73fulcrumed upon the frame of the machine at 74; and connected to theframe (36 by a link 75 (see Figs. 2 and 3). A cam block 76 having acircumferentially arranged cam groove 77 therein, and co-operating witha stud 78 on the lever 73, is provided for actuating the lever to thereby reciprocate the frame 66. The cam block 76 is mounted. upon anupright cam shaft 79 journaled in suitable brackets mounted u on .theframe of the machine, and said she t is driven from the die actuatingshaft 25 by a sprocket chain 80 I trained over sprocket wheels 81 and 82mounted upon the die actuating shaft 25 and cam shaft 79, respectively.

The sprocket wheel 81 is keyed to the shaft 25 and rotates continuouslytherewith.

As has been heretofore explained, the main drive gear wheel 26 (see Fig.4) is loose upon the shaft 25 and is clutched thereto by the clutch 27which may comprise a clutch collar 84L slidably mounted on the hub ofthe gear wheel and having the clutch pins 27 thereon which slide throughthe sprocket wheel 81 and enter sockets in the gear wheel 26. 4 A clutchlever 83 is provided for clutching the shaft 25 to the gear wheel 26,and said clutch lever engages with the clutch collar 84. In case thematerial becomes jammed in any of the units, or in case any of themechanisms thereof become disabled, the attendant may throw that unitout of action by moving the clutch lever 83 in the proper direction,thereby unclutching the shaft 25 of that unit from the gear wheel 26.

After the slotted strips A have been formed, they are inserted into theassembling frame by mechanism which will now be described. Immediatelybelow the lower edges ways 85 are in alignment with each other directlyunder the position occupied by the slotted strips above them, and theirdischarge ends extend at right angles thereto and are parallel with eachother, being spaced apart a distance equal .to' the spacings of thenotched strips of the finished egg case filler. From this it will beobserved that the sheet A, which has passed through the machine in oneplane, is severed into individual strips. and the strips are deflectedfrom said plane intoparallel planes at right angles thereto, and in thislatter relation, they are fed into the assembling frame which will bedescribed presently. I

Secured to the cutting board, above the path of travel taken by thesheet A, are guide finger-s85, one for each slotted strip A, and

secured to the upper ends of th'echutes 85 are guide fingers 85 whichserve to prevent the slotted strips from falling or bending forward fromthe cutting board while being inserted into the chutes 85 by the stripinserting fingers. The fingers 85 also act as stops from the guidewaysinto the assemblingframe. Above 'theassembling frame is a stripinsertingrod 86 which occupies a. position above and out of alignment with thepaths of movement taken by the slotted strips during the interval thatthe strips are being inserted into the chutes 85. Said strip insertingrod is carried by arms 87 mounted upon a rock shaft 88 which isjournaled in brackets carried by the frame'of the machine, and drivenfrom the cam shaft 79 in timed relation to the movements of-thereciprocating frame 66.

As shown, the rock shaft 88 is equipped with a gear 89 thereon whichmeshes with a segmental rack 90 rotatably mounted upon a stud shaft 91.From the segmental rack 90 extends an arm 92 which bears a roller 93that co-o crates with a cam groove 94 formed in the ace of a cam block95 which is mounted on the shaft 79. The arrangement of the parts justdescribed is such that once during each complete rotation of the shaft79, the intermeshing segmental racks 89 and 90 are oscillated back andforth once and the arms 87 and therewith the strip inserting rod 86 aremoved up and down once, whereby the slotted strips, which previouslyhave been moved down into position to be engaged by the strip insertingrod 86, are thereby fed into the assembling frame at right angles to'theposition they formerly occupied.

immediately below the chutes 85 is the assembling frame 96 (see Figs. 9,12 and 13). Said frame comprises two companion sections 9797 that haveparallel vertically extending transversely arranged guideways 98 inalignment with the discharge ends of the chutes 85 for the reception ofthe slotted strips A and parallel horizontally extendin channels 99 ofless width than the guideways and intersecting them. The channels act toguide the notched strips through the slots of the slotted strips.

In the upper portion of the assembling frame (see Fig. 12) isillustrated one of the slotted strips A, and through each of the slotsof said strip is shown one of the notched strips B in cross sect-ion,the notched strips, while contained in the assembling frame, be? ingbent or curvedalong lines running lengthwise of themselves. The verticalguideways 98 are provided by forming deep grooves in the opposing facesof the two sections 97 The horizontal channels are provided by forminghorizontally extending deep grooves in the opposing faces of the twosections 97. When the two sections are brought together,

as shown in Fig. 12, the companion horizontal grooves form the channels99, which in cross section, correspond generally to the shape of theslots 8 in the slotted strip A; At the bottom of the two sections 97 areshoulders 100, or other stops, forsupporting the slotted strips A in theassembling frame with the slots 8 of said strips in register with thechannels 99. It will be understood, therefore, that when the notchedstrips B are bent or curved into a shape to correspond the main dieactuating shaft 25.

with the curved walls of the channels 99, the

notched strips may be inserted through said channels from end to end andconsequently inserted through the slots 8 of the slotted wheels 104mounted upon the lower ends of the shafts 101.

Operative connections are provided between the shafts 101 and the twosections 97 of the assembling frame which, as shown, comprise cam blocks105 mounted on the shafts 101 and having cam grooves thereinco-operating with pins or studs 106 carried by the two sections of theassembling frame. The pins or studs 106 are illustrated as mounted onbrackets 107 secured to the outer sides of the two sections 97. The twosec tions of the assembling frame are guided in horizontally extendingguide members 108, whereby they move in a parallel line at right anglesto their length.

The two sections are here shown as provided with shoes 109 which travelin the guideways of the guide members 108. It will be observed thatduring each complete. rotation of the shafts 101, the two sections ofthe assembling frame are drawn apart to discharge a completed egg casefiller and moved together in position to receive the strips forassembling another filler. The cam grooves in, the cam 105 containconcentric portions co-operating with the pins or studs 106 to permitthe two sections of the assembling frame to remain in closed positionduring the major portion of one complete rotation of the shafts 101. Thetwo sections are separated only for such an interval of time as willpermit the completed egg case filler to drop out of the assemblingframe. The shafts 101 are driven from the cam shaft 79 and rotate intimed relation to said shaft and As shown in Figs. 2 and 3, the drivemechanism between the camshaft 79 and the shaft 101 comprises a sprocketchain 110 trained over sprocket wheels 111 and 112, one of which ismounted on the cam shaft 79, and the other on one of the shafts 101.

In order that each completed egg case filler may be effectivelydiscarged from the assembling frame when the two sections thereof aremoved apart, stationary horizontal rods 113 are provided which extendstrips. 7 t is to be observed by reference to 'Figs. 12 and 1,3 thatwhen the two sectionsof the assembling frame are moved apart to releasethe completed egg case filler therefrom, the rods 113 engage the edgesof the notched strips of the-egg case filler, thereby stripping it fromtheassembling frame, and

when the supports 100 atthe bottom of the two sections of the assemblingframe have been moved from underneath the completed egg case filler, thelatter drops between the opposing rods 113 and falls free and clear ofthe two sections of the assembling frame. Adjacent the die 41 whichoperateson the sheet- B are cutting disks or knives 115 (see Figs. 2'and8) which co-operate with a roller 116 to slit or sever the sheet B intoindividual notchedribbons or strips B. The cutting disks orknives115 aremounted on a ver tically extending rod 117 carried in a supportingbracket 118 adjustably mounted in a frame member 119 carried'by the mainframe of the machine. Adjustment means is provided, as seen in Fig. 8,for fastening the racket 118 .to the frame member 119. The cuttingdisksor knives 115 are spaced equidistant and disposed in such relationto the sheet B as to sever the same midway between the ends of eachopening 8', thereby forming the notches s in the ribbons or strips B.

Means are provided for feeding the notched ribbons or strips B into theassembling frame in timed relation to the other operating mechanism ofthe machine, and

3 planes, and, at the same time, said feed} mechanism is arranged tobend the notched rib- I with a convex circumferential facel said feedmechanism is intermittently operated from the main or die actuatingshaft 25 and is set into motion as soon as the slotted strips A havebeen inserted into the assembling frame in position to receive thenotched strips. Said feed mechanism is also arranged to turn the ribbonsor strips B along their horizontal axes from a vertical plane intospaced superposed horizontal bons or strips B into trough-likeconfigurations, in which condition they are inserted into the assemblingframe.

.As shown, the feeding mechanism for each' ribbon or strip B comprisestwo companion rollers 120 and 121 (see Figs. 9 and 15), one of which isformed-with a concave circumferential face and the other of which isformed rollers are mounted upon shafts 122 and 123 journaled in framemembers 124 carried b the main frame of the machine, and the rol ers 121are positively driven in an intermit- The transmitted from the rack barto the shafts of the rollers only when the rack bar is being movedin-one direction.

It is to be observed from Figs. 2, 9 and 10 that all of the feed rolls120 and 121, with 'the exception of the uppermost set, are arranged toform the convex part of the troughlike configuration given to thenotchedrib- Ibons or strips B, on the upper sides thereof,

whereas the uppermost set" of feed rolls is arranged-to bend theuppermost ribbon in the opposite direction so as to have the con- 7 vexside face in the opposite direction.

In order to rotate the roll 121 of the upper- --most set in the properdirection to feed the uppermost ribbon or stri in the same direction asthe remaining ri bons or strips are fed, the uppermost set of rolls-andtheir driving pinion- 125 are placed on the opposite side of the rackbar 126 (see Fig. 10) which is provided with rack teeth on both sides.ft is to be observed from an inspection of Figs. 9 and 10 that when therack bar 126 is moved upwardly, the feeding rolls are rotated in thedirections of the adjacent arrows, and, consc quently, the notchedribbons or strips A are fed into the assembling frame, but that when therack bar is moved downwardly, the feed rolls remain at rest, since theclutches between the pinions 125 and the roll shafts 123 I operate toclutch the pinions and shafts together only when the pinions aremovedjin the one'direction.

The rack bar 126 is guided upon the frame member 124, as, for instance,by a pin or roller Ill 127 which engages in a slot 128 in the rack bar.The rack bar is reciprocated by the main shaft 25 in timed relation tothe other mechanism of the machine by means here shown as comprising abell crank lever 129 (see Fig. 5) fulcrumed upon the frame of themachine and connected to the crank Wheel 54 by a link 130, link 58,lever 55 and link 56.

From the above, it will be understood that after the slotted strips Ahave been fed into the assembling frame with the slots 8' in registerwith the channel 99 thereof, the bent or curved portions of the notchedstrips B are fed into the channels of the assembling frame and throughthe slots of the slotted strips. The arrangement and proportions of theparts are such that the notched ribbons or strips are placed in theassembling frame with their notches n at the intersections with Ill the,slotted strips, 'trated in'Fig. 19.

While the exact shape of the slots 8 is im-' which position isillusmaterial, the one shown enables the notched ribbons or strips to bereadily inserted through the slots of the slotted strips and interlocktherewith-when released from their bent or bowed condition. The slotsshown are of a configuration somewhat in the nature of theletter D, thelateral extensions 8 there of permitting the edge portions of thenotched ribbons or stri s B to enter the. D slots when the notched ribons or strips are maintained intheir bent or bowed condition. It is tobe observed that when the notched strips are released from the bowedcondition shown in Fig. 19, their inherent resiliency serves to stripshave been inserted into theass'embling straighten them out into the flatcondition shown in Fig. 17 wherein the strips interlock at theintersections with the slotted strips. i

- Severing means are provided for cutting the assembled portions of thenotched ribbons or strips B from the unassembled portions thereof, and,as shown, said severing means comprise companion knives 131 (see Fig.11) secured to one end of the assembling frame, adjacent the ends of thechannels 99 therein. Each knife is secured to one section of theassembling frame and extends across the end of the other section anddownwardly, asis clearly seen in Fig. 11. It is to be observed that whenthe two sections of the asstrips from the unassembled ones, thecompleted assembled egg case filler is free to fall and does'drop out ofthe assembling frame,

as is clearly seen in Fig. 2. Conveniently, a conveyor 132 may beprovided underneath the assembling frame for conveying the assembled eggcase fillers away from the machine.

In the operation of the machine, the egg case filler material is actedupon by the dies adjacent the receiving end of the machine, and theslots-s, notches n and double notches n are formed therein. During theinterval that the strip inserting frame 66 occupies itslowermost-position, the feed rollers 52 and 53 feed the slotted sheet Ainto position behind said frame, and thereafter the canr76 swingsupwardly the arm 7 3, thereby lifting the frame 66, and during theupward movement of said frame, the cutting disks or knives 69 cut theadjacent portion of the sheet A into individual slotted strips A.

The cam 76 thereafter swings the lever 73 downwardly, thereby moving theframe 66 downwardly, whereupon the strip inserting fingers 71 force thestrips part way through the chutes orguideways where they are frame, therack bar 126 is moved upwardly thereby rotating the feed rolls 120 and121, and said feed rolls draw the sheet B towards the assembling frame,whereby the sheet is slit as it encounters the cutting disks and 116.The ribbons or strips B thus formed are turned into spaced superposedhorizontal planes and bent or bowed upon themselves by the feed rollsand 121, and-the bent ends of the ribbons or strips B are inserted intothe channels of the assembling frame and through the slots of theslotted strips.

Immediately thereafter the two sections of the assembling'frame aremoved apart by the cams 105, during which time the knives 181 sever theassembled portions of the notched strips from the remainder of theribbons B. As the two sections of the assembling frame separate, thebent or bowed notched strips straighten out under their inherentresiliency, whereby the notched portions interlock with theslottedstrips and the completed egg case filler drops from theassembling frame upon the conveyor which carries it away from themachine.

It is to be observed that all of the strips for'making a complete fillermay be slit from two sheets. This is a particular advantage,

since it requires merely the handling of two rolls of material-Furthermore, by running the two sheets through the machine with onesheet disposed above the other in a vertical plane, the. punchings fromthe sheets fall away-from the sheets and dies, and, conse quently, donot interfere with the action of the dies. Moreover, the several unitswhich comprise the complete machine may be timed to operate in someregular sequence, whereby the punching operations of each unit takesplace when the punches of the other units are at rest. By reason of thisarrangement, power is economized and the wear and tear of the machine isgreatlyilessened.

More or less variation of the exact details of construction is possiblewithout departscribed, but intend, in the following claims,
